  h 
  smaller, 
  the

  shorter, 
  aiul 
  the 
  

   lower

  The 
  e^'o 
  is 
  very 
  large, 
  and 
  is 
  less 
  

   than 
  its 
  diameter 
  from 
  the 
  snout. 
  The 
  nostrils 
  are 
  double 
  ; 
  

   the 
  posterior 
  is 
  larger, 
  oval, 
  elongated, 
  nearly 
  vortical, 
  and 
  

   on 
  a 
  plane 
  rather 
  below 
  the 
  upper 
  margin 
  of 
  the 
  eye, 
  and 
  at 
  

   the 
  anterior 
  extremity 
  of 
  the 
  supra-orbital 
  ridge 
  ; 
  the 
  anterior 
  

   is 
  circular, 
  and 
  very 
  near 
  the 
  posterior. 
  The 
  mouth 
  is 
  large, 
  

   with 
  thin 
  lips 
  ; 
  the 
  upper

   with 
  a 
  double 
  series 
  of 
  small, 
  conical, 
  pointed 
  teeth 
  ; 
  in 
  front, 
  

   and 
  between 
  these 
  rows, 
  but 
  belonging 
  to 
  neither, 
  though 
  

   nearest 
  the 
  postoiior, 
  are 
  two 
  large 
  canine 
  teeth, 
  conical, 
  

   pointed, 
  recurved 
  and 
  directed 
  backv*'avds. 
  The 
  lower 
  jaw 
  

   has 
  a 
  double 
  series 
  of 
  minute, 
  pointed 
  teeth 
  in 
  front, 
  while 
  

   behind 
  there 
  is 
  only 
  a 
  single 
  row, 
  and 
  the 
  teeth 
  are 
  larger. 
  

   The 
  tongue 
  is 
  large, 
  flat, 
  rounded 
  and 
  free 
  in 
  front. 
  The 
  

   preopercle 
  is 
  rounded 
  at 
  its 
  angle, 
  with 
  a 
  crenated 
  margin. 
  

   The 
  opercle 
  terminates 
  in 
  two 
  minute, 
  flattened 
  points. 
  The 
  

   anterior 
  dorsal 
  fin 
  begins 
  behind 
  the 
  root 
  of 
  the 
  pectoral, 
  and 
  

   has 
  eight 
  spinous 
  rays, 
  received 
  in 
  a 
  sheath 
  ; 
  the 
  second 
  and 
  

   third 
  being 
  longest. 
  The 
  posterior 
  has 
  one 
  spinous 
  and 
  28 
  

   soft 
  rays; 
  the 
  first 
  very 
  short 
  and 
  closely 
  joined 
  to 
  the 
  second; 
  

   the 
  scales 
  ascend 
  high 
  up 
  on 
  its 
  roots, 
  and 
  make 
  a 
  partial 
  

   sheath. 
  The 
  pectoral 
  is 
  small, 
  arising 
  at 
  the 
  termination 
  of 
  

   the 
  opercle. 
  The 
  ventral 
  is 
  short, 
  but 
  tolerably 
  broad. 
  The 
  

   anal 
  is 
  short 
  ; 
  it 
  has 
  one 
  delicate 
  spinous 
  and 
  nine 
  soft 
  rays. 
  

   The 
  caudal 
  is 
  moderately 
  broad, 
  nearly 
  straight 
  behind. 
  The 
  

   lateral 
  line 
  runs 
  along 
  the 
  upper 
  fourth 
  of 
  the 
  body 
  as 
  far 
  as 
  

   the 
  second 
  dorsal, 
  where 
  it 
  curves 
  down 
  to 
  the 
  median 
  plane, 
  

   and 
  continues 
  to 
  the 
  end. 
  The 
  whole 
  animal 
  is 
  silvery 
  white 
  

   except 
  the 
  fins, 
  which 
  are 
  more 
  or 
  less 
  yellowish 
  ; 
  the 
  pupil 
  

   is 
  deep 
  blue, 
  and
